Vybz Kartel ruled dancehall once more in 2015. From the start of the year ’til finish, the Worl’ Boss just kept coming with hits, par for the course for an artist without peer. Many of the best tracks from his 2015 campaign originally appeared on Viking (Vybz is King), an 11-track EP that could have been sold as an LP with a few more songs instead of skits. Among them were “Dancehall,” already one of dancehall culture’s great anthems, and easily the year’s biggest track in the dancehalls; the sweetly melodic “Gon Get Better”; and the autobiographical “Unstoppable.” —Jesse Serwer
